Step 1) The method which will perform Reflection of image.
public Bitmap getRefelection(Bitmap image)
{
//The gap we want between the reflection and the original image
final int reflectionGap = 4;
//Get you bit map from drawable folder
Bitmap originalImage = image ;
int width = originalImage.getWidth();
int height = originalImage.getHeight();
//This will not scale but will flip on the Y axis
Matrix matrix = new Matrix();
matrix.preScale(1, -1);
//Create a Bitmap with the flip matix applied to it.
//We only want the bottom half of the image
Bitmap reflectionImage = Bitmap.createBitmap(originalImage, 0, height/2, width, height/2, matrix, false);
//Create a new bitmap with same width but taller to fit reflection
Bitmap bitmapWithReflection = Bitmap.createBitmap(width
, (height + height/2), Config.ARGB_8888);
//Create a new Canvas with the bitmap that's big enough for
//the image plus gap plus reflection
Canvas canvas = new Canvas(bitmapWithReflection);
//Draw in the original image
canvas.drawBitmap(originalImage, 0, 0, null);
//Draw in the gap
Paint deafaultPaint = new Paint();
canvas.drawRect(0, height, width, height + reflectionGap, deafaultPaint);
//Draw in the reflection
canvas.drawBitmap(reflectionImage,0, height + reflectionGap, null);
//Create a shader that is a linear gradient that covers the reflection
Paint paint = new Paint();
LinearGradient shader = new LinearGradient(0, originalImage.getHeight(), 0,
bitmapWithReflection.getHeight() + reflectionGap, 0x70ffffff, 0x00ffffff,
TileMode.CLAMP);
//Set the paint to use this shader (linear gradient)
paint.setShader(shader);
//Set the Transfer mode to be porter duff and destination in
paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN));
//Draw a rectangle using the paint with our linear gradient
canvas.drawRect(0, height, width,
bitmapWithReflection.getHeight() + reflectionGap, paint);
return bitmapWithReflection;
}
Step 2) Call this method in a ImageView
as
Bitmap originalImage = BitmapFactory.decodeResource(getResources(),
R.drawable.trisha);
//Create an Image view and add our bitmap with reflection to it
ImageView imageView = new ImageView(this);
imageView.setImageBitmap(getRefelection(originalImage));
//Add the image to a linear layout and display it
LinearLayout linLayout = new LinearLayout(this);
linLayout.addView(imageView, new LinearLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT ) );
// set LinearLayout as ContentView
setContentView(linLayout);
The Output would as follows:
The image with Reflection at the bottom of the image |
